To all whom t may concern: l

Be it known that I, Fey L. Warauman, ,pa citizen of the United States,residing at Endicott, in the county of Broomeand State of'New Yorkfhaveinvented certain new and useful Im rovements inApparatus forSeparatinghl `uspended Solids from Liquids;`

The cylinder l is'provided atwitsfends with suitable heads -lb whichstillen and support the ends of the cylinder and-are provided `withcentral openin s 1 The cylinder is furthermore prefera ly provided Awithexterior annular4 reinforcing hoops ld which strengthen the'd rum andalso support it upon ,groovedv rollers 2 mounted o n'stub shafts 2'journaled in bearings 2* mounted on suitable beams as 2 or othersuitable foundation. These rollers :2 support the cylinder in preferablya horizontalposition,

above areeeiver (not shown) into which the liquid escapingfrom.thecyliuder is directed. l

The cylinder is provided on its interior with a series of radiallydisposed wings or partitions l' ywhich'preferably extend fromtheperiphery of the cylinder nearly to the edges o'l 'the openings l,but leave an lan,-4 nular open space Or'chamberaXially of and within thecylinder for the accommodation of the conl'eyer, hereinafter referredto, for removing solids #from-1 the cylinder.I The wings 1f may `loemade of sheet metal, such `as Steel or brass ,and are of suilicierit4thick? 'ness to enable them to support thesolids which may be depositedthereon or carried" up thereby. inthe cylinder, may be reticulatedfanilare shown as slotted lout the slots in the' w'n'gs preferablyexteudThese Wings radially of the cylinder, or transversely of the wings, asshown at 1B, instead of lon tudinally thereoffso that y the lsolids`will Vslidefmore readily off of the `Wings when; the apparatus is inoperation.

The fluid containingV solids insuspensitalf" may be introdud into oneendof the cylinder by means of a Apipe P which ,enters the.

cylinder' through theA opening 1' inthe ad-f jacent head l", asindicated in Figs. .1 `and 2. i The fluid may be admitted in any con-Q,

veulent manner.

The grooved rollers 2l are` arranged pairs beneath `the cylinder, asindiciltedin FigsrZ and 3, so as t'o support it while pe`rv Arnittingits rotation. The] cylinder-may b'e l Y rotated hy any suitable means.In the elifA ample shown,l itisfprovidedwithan'annulalf l gear 3 on its'lnletxend meshin with a pineion 3' on a shaft'B" Journale '3? mountedon the frarningasndicatd ing A Fig'. 2,4 or other convenient supp0rtf"il-lll?4 i 'their' shaft 3- carries a worm wheel' 34 mes with a worm 3,on a `shaft 3t which sha may be driven by a motor 3,'or other suitablemeans.

Extending longitudinally of and within .the cylinder 1 is an 'endless'conveyer 4, whichjmay be. of any suitable construction. Asv shown 'thisconvcyerruns over rollers 4 mounted in suitable bearings 4" attachedv tothe opposite ends a bar or frame 4, slip* extend longitudinally of* andwithin y-linder, and are suitably supported at ends'upon' the framing ofthe appa',-

,rtuja as indicated in the drawings; so that y the conveyer 4 may, ifdesired, be bodily l V.':withdrawn from the cylinder for repairs.

" When the conveyer is in operative position within the cylinder, as inFigs. 1 and a' shaft 4 journaled in suitable-bearin be rotated by 2, theoutermost roller 4 may y the main framing as indicated in the rawingsand having a beveled gear 4 on one end I c'shing with a beveled gear 3on the adjacentend of vthe shaft 3b asindicated in the drawings. Byproperly proportioning the gearing the conve er may be driven at `any Adesired speedre ative to the rotative moveinent of the lcylinder 1, 4and preferably in such directiomthat the upper run of the conveyer movesa'way from'the inlet pipe'P.

The conveyer 4 extends outside io terial over theoutermost drum 4* onto`an underlyin 'rollers 5 journaled in" arings 5h on the framing 5. Anapron maybearranged beneath th'e outer end of convcyer 4 todirect'the's'olids onto conveyer 5.

The 'conveyer 5 may`beconstructed and "mountedlike conv'eyerv 4 ifdesired, and may be operated' by Ameans'of `a pulley 5'1 on the outerroller 5b driven by a 5s orna motor 5; or in' any other suitable manner.
